This　paper　presents　a　design　method　for　a　multi-transmitter　wireless　power　transfer　(WPT)　system　that　aims　to　achieve　stable　and　high-power　transfer　efficiency　(PTE)　across　a　wide　range.　The　proposed　method　utilizes　a　Genetic　algorithm　(GA)　to　obtain　the　parameters　of　three　transmitter　coils　that　can　cope　with　different　distances.　Experimental　results　demonstrate　that　the　presented　3-transmitter　coils　outperform　the　conventional　transmitting　coil,　especially　in　scenarios　where　the　WPT　system　operates　under　misalignment　and　over　longer　distances.　Even　when　the　receiving　coil　is　moved　within　a　distance　range　of　30-130mm　and　an　offset　range　of　0-130mm,　the　PTE　of　the　system　remains　above　70%　throughout　the　entire　range.　©　2023　IEEE.
